Clean Notice Clean the engine before you start
engine maintenance. Obey the correct procedures.
Contamination of the fuel system will cause
damage and possible failure of the
engine. Notice The engine and other components
could be damaged by high pressure washing
systems. Special precautions must be taken if
the machine is to be washed using a high
pressure system. Make sure that the alternator,
starter motor and any other electrical
components are shielded and not directly cleaned
by the high pressure cleaning system. Do not aim
the water jet directly at bearings, oil seals or
the engine air induction system.

• Before carrying out any service procedures that
  require components to be removed, the engine must
  be properly cleaned.
• Cleaning must be carried out either in the area
  of components to be removed or, in the case of
  major work, or work on the fuel system, the
  whole engine and surrounding machine must be
  cleaned.
• Stop the engine and allow it to cool for at least
  one hour. DO NOT attempt to clean any part of
  the engine while it is running.
• Make sure that the electrical system is isolated.
• Make sure that all electrical connectors are
  correctly coupled. If connectors are open fit the
  correct caps or seal with water proof tape.
• Cover the alternator with a plastic bag to
  prevent water ingress.
• Seal the engine air intake, exhaust and breather
  system.
• Make sure that the oil filler caps and dipstick
  are correctly installed.
• Use a low pressure water jet and soft bristle
  brush to soak off caked mud or dirt.
• Apply an approved cleaning and degreasing agent
  with a brush. Obey the manufacturers
  instructions.
• Use a pressure washer to remove the soft dirt
  and oil. Important DO NOT aim the water jet
  directly at oil seals or electrical connectors
  and electronic components such as ECU
  (Electronic Control Unit)'s, alternator or fuel
  injectors. DO NOT place the jet nozzle closer
  than the specified distance to any part of the
  engine or exhaust system.

1. Make the machine safe.
2. Get access to the engine compartment (if
   applicable)
3. Check the engine and the area below for oil
   leaks.
4. Close the engine cover (if applicable).
5. If necessary, contact your JCB dealer.

This test is used to diagnose suspected poor
compression in one or more of the engine
cylinders. Use ServiceMaster to control the test.
Engine Oil Pressure Use the following procedures
to measure the engine oil pressure. Several
factors can influence the engine oil pressure,
the following conditions are assumed

• The correct engine oil has been used. Refer to
  PIL 15-21-00.
• The engine oil level is correct. Refer to PIL
  75-03-03.
• Make sure that the engine is safe to work on. If
  the engine has been running, let it cool before
  you start the service work.
• Get access to the engine.
• Disconnect the electrical connector to the oil
  pressure switch, remove the switch from the oil
  cooler housing.
• Install a suitable adaptor into the vacant
  pressure switch port (M10 x 1.5mm thread) and a
  pressure test gauge. Make sure that the gauge
  has a sealing washer as shown.
• Special Tool Pressure Gauge (0-70 Bar) (Qty. 1)

• Low oil level - typically evident as a loss of
  pressure when operating on uneven ground or on a
  gradient.
• Blocked oil filter - a blocked filter will show
  as a gradual loss of pressure.
• Blocked suction strainer (pick-up pipe) -
  typically evident as low pressure on start up,
  if the blockage frees itself in the sump, the
  pressure will pick up to normal.
• Coolant in the oil - coolant in the lubricating
  oil will show as a milky discolouration of the
  oil and an increase in oil level. Check for
  damaged core plugs, lubricating oil cooler,
  cylinder head and/ or gasket.
• Fuel in the oil - fuel in the oil will result in
  thin' black lubricating oil, the oil will also
  have a diesel fuel smell. Check the fuel
  injection pump (FIP) shaft seal, piston ring
  wear, lift pump diaphragm damage or injector
  leakage if fuel is evident in the oil.
• Damaged oil pump - oil pressure will be high at
  low oil temperature but fall when oil becomes
  hotter.

• Oil pressure switch
• Sealing washer
• Start the engine and allow a few seconds to gain
  oil pressure, increase the engine revs to the
  rated speed. Record the pressure gauge reading.
  Check that the pressure is within the specified
  tolerance.
• Refer to PIL 15-00-00.
• Remove the pressure gauge and install the
  pressure switch.
• High Lubrication Oil Pressure
• High oil pressure will be evident when starting
  in cold conditions. Typically the pressure will
  be 1 to 2 bar and higher in cold operation, the
  pressure should drop when the engine reaches
  normal operating temperature.
• If the pressure remains high when operating
  temperature is achieved, check the oil level, if
  this is correct, suspect the oil pressure relief
  valve is at fault.
• Low Lubrication Oil Pressure
• Several factors can be the cause of low
  lubricating oil pressure

   reverse order starting at bolt 10. The bolts MUST
   NOT be re-used. Discard the bolts.
2. Install the four temporary lifting bolts.
   Carefully separate the bedplate from the
   crankcase. Use suitable lifting equipment (if
   the bedplate is lifted manually, two people will
   be required). DO NOT use a lever to separate the
   bedplate.

• Put labels on the thrust washers to make sure
  that they are installed in the correct positions
  during assembly.
• Carefully lift out the bearing shells.

• D Main bearing shells
• It is recommended that the bearing shells are
  replaced. If however they are to be used again,
  put labels on the shells to make sure that they
  are installed in their original positions during
  assembly.
• Inspect the crankshaft and main bearings for
  damage and excessive wear.
• Refer to PIL 15-12-00.

• Before Installation
• Clean off all traces of the old sealant compound
  from the crankcase and bedplate mating faces.
• Use a suitable degreasing agent to carefully
  clean the main bearing saddles in the bedplate
  and crankcase. Take care not to block the oil
  ways or the piston cooling jets.
• Consumable Cleaner/Degreaser - General purpose
  solvent based parts cleaner
• Important Cleanliness is of the utmost
  importance. Blocked oil-ways or oil jets will
  cause engine failure. Before you install the
  crankshaft make sure that ALL oil-ways and jets
  are clear and free from debris.
• Install
• 1. The installation procedure is the opposite of
  the removal procedure. Additionally do the

• Make sure that all items are clean and free from
  damage and corrosion.
• Install the upper bearing shells as follows
• Figure 155.

• Use suitable lifting equipment (if the crankshaft
  is lifted manually, two people will be
  required), to carefully lower the crankshaft
  into the crankcase. DO NOT rotate the
  crankshaft, the bearing shells can become
  dislodged. Make sure that the connecting rods
  are located onto the crankshaft journals.
• Make sure that the connecting rods are located
  onto the crankshaft journals.
• Make sure that the crankshaft is installed so
  that the engine timing is correct. The single
  mark on the crankshaft drive gear must locate
  between the two marks on the camshaft drive
  gear.

  engages into the slot as shown.
• Make sure that the oil-way holes in the bearing
  saddles align with the holes in the bearing
  shell. If the holes are even partially
  misaligned the piston cooling oil jet will be
  restricted, causing the engine to fail.
• Lubricate the upper bearing shells with clean
  engine oil.
